Brickset has posted images of the Series 5 wave of the LEGO Mixels which shows all nine characters in the wave as well as the Max model for each tribe. These were spotted at Toy Fairs earlier in the year but photography of them were prohibited.
The Klinkers have a brown and grey color scheme and has a very steampunk feel to them. The Frosticons make their return with three more characters from the tribe. Finally, the Lixers are mainly yellow with their main features being their tongue.
The Series 5 LEGO Mixels are set to be released in June.
Update: The images were first found on the Mixels Wiki.
